Abstract- Wireless power transfer technology has more advantages over conventional means of power transfer and its generation, thus it has received more attention in the few decade and has been employed to apply to a wide range of applications, ranging from low power required for biomedical applications to railway vehicles with efficiency up to 95% or higher in some prototype systems. Magnetic wireless power transfer systems rely on magnetic field coupling to transfer electric power between two or more magnetically coupled coils.
The main objective of wireless power transfer for electric vehicles is to transfer power within a smaller range. The wireless power transfer system consists of transmitter and receiver part which are separated by small distance of about 3cms. Therefore the transfer can be seen as the receiver receives the power to run the motor. Wireless power transmission technology uses time varying electromagnetic field. This electromagnetic field is created around the free space which carries a steady current of charges creating a magnetic field around it and this field contains energy in it and the EMF is generated between the coils and it is transmitted to the receiver.

Keywords— Wireless power transfer, ARDUINO microcontroller, transmitter section, receiver section.

I. INTRODUCTION

The proposed system implements ARDUINO microcontroller based wireless power charging or generation methodology for charging electric vehicles. This system consists of ARDUINO microcontroller, inductive coils, vehicle prototype module.
Solar panel system is implemented to transfer the power to the primary coil. Solar panel is connected to the battery directly. Then it can drive into the rectifier circuit through an inverter. The inverter circuit is connected with ARDUINO micro controller to switching the power supply. The switched power is fed into the inverter through driver circuit. The coil has high capacity of inductance which can able to transfer the power with high frequency. It is named as the high frequency coil. Those power input are connected to the high frequency primary coil which is laid under the road segment.
